You can see the results of their work here: The Design Of HTML5. Each volunteer transcribed about ten minutes of the talk, which equates to about an hour’s work.

As it turned out, the Fronteers folks had commissioned a transcription from Casting Words, the service built on Amazon’s Mechanical Turk. You can see the result—not bad. I’ve used Casting Words in the past to get transcriptions done although lately I’ve found they take far too long for somewhat inconsistent results.

I think that, for the best results, you can’t beat hiring a professional transcriber. But, in lieu of that, I think the aforementioned volunteers did a great job, for which I am very grateful.
